International audience Determining the year-round distribution and behaviour of birds is necessary for a betterunderstanding of their ecology and foraging strategies. Petrels form an important componentof the high-latitude seabird assemblages in terms of species and individuals. The distributionand foraging ecology of three sympatric fulmarine petrels (Southern FulmarFulmarus glacialoides, Cape Petrel Daption capense and Snow Petrel Pagodroma nivea)were studied at Adelie Land, East Antarctica, by combining information from miniaturizedsaltwater immersion geolocators and stable isotopes from feathers. During thebreeding season at a large spatial scale (c. 200 km), the three species overlapped in theirforaging areas located in the vicinity of the colonies but were segregated by their dietand trophic level, as indicated by the different chick d15N values that increased in theorder Cape Petrel < Southern Fulmar < Snow Petrel. During the non-breeding season,the three fulmarines showed species-specific migration strategies along a wide latitudinalgradient. Snow Petrels largely remained in ice-associated Antarctic waters, Southern Fulmarstargeted primarily the sub-Antarctic zone and Cape Petrels migrated further north.Overall, birds spent less time in flight during the non-breeding period than during thebreeding season, with the highest percentage of time spent sitting on the water occurringduring the breeding season and at the beginning of the non-breeding period beforemigration.
